Boron - Wikipedia
Boron is similar to carbon in its capability to form stable covalently bonded molecular networks. Even nominally disordered boron contains regular boron icosahedra which are, however, bonded randomly to each other without long-range order.Crystalline boron is a very hard, black material with a melting point of above 2000 C.
